（结对作业）基于Unity 3D游戏引擎开发的“打砖块”游戏

来源：互联网发布：免费的分身软件编辑：程序博客网时间：2024/06/10 03:23

游戏简介：游戏在传统的打砖块游戏的基础上增加的3D的效果。游戏的操作非常简单，简单的左右方向键控制，以及鼠标对视角的控制。

编写人员：朱俊璋，王士溥

开发工具：Unity3D 4.3

开发语言：C#

计划

任务分工：后台的游戏功能的具体实现和测试，后台代码的编写和调试朱俊璋

游戏前端界面的设计和游戏逻辑功能的创想王士溥

开发时间：2周

功能简介：3D打砖块小游戏，实现基本功能，在游戏中可以通过鼠标调节camera视角以及位置——左键+移动鼠标-水平移动；右键+移动鼠标-摄像头倾斜角度；滚轮-缩放镜头。

运行游戏：

BreakoutGame类：该类是游戏的主功能类，游戏的初始化和游戏界面的渲染都在此类中。该脚本绑定到游戏Main Camera组件中，使游戏在一开始时就调用此脚本。

Ball类:该类绑定在BallPre.prefab游戏组件中，用于控制小球的速度。

using UnityEngine;using System.Collections;public class Ball : MonoBehaviour {    public float maxVelocity = 20;//珠球最大速度.    public float minVelocity = 15;//珠球最小速度.void Awake () {        rigidbody.velocity = new Vector3(0, 0, -18);//小球初始速度.}void Update () {        //控制小球的速度在15—20之间.        float totalVelocity = Vector3.Magnitude(rigidbody.velocity);//得到珠球的总的速度.        if(totalVelocity > maxVelocity){            float tooHard = totalVelocity / maxVelocity;            rigidbody.velocity /= tooHard;        }        else if (totalVelocity < minVelocity)        {            float tooSlowRate = totalVelocity / minVelocity;            rigidbody.velocity /= tooSlowRate;        }//print(rigidbody.velocity);        //若珠球的z坐标小于-3,游戏结束.        if(transform.position.z <= -3){                        BreakoutGame.SP.LostBall();            Destroy(gameObject);//消除游戏组件.        }//print (rigidbody.velocity);}}

Paddle类：该脚本绑定到游戏组件paddle中，用于调节控制板条的移动。

using UnityEngine;using System.Collections;public class Paddle : MonoBehaviour {    public float moveSpeed = 20;void Update () {//获取水平方向,得到移动距离.float moveInput = Input.GetAxis("Horizontal") * Time.deltaTime * moveSpeed;        <span style="white-space:pre"></span>transform.position += new Vector3(moveInput, 0, 0);//控制板条移动范围.        <span style="white-space:pre"></span>float max = 14.0f;        <span style="white-space:pre"></span>if (transform.position.x <= -max || transform.position.x >= max)        <span style="white-space:pre"></span>{          <span style="white-space:pre"></span>  <span style="white-space:pre"></span>float xPos = Mathf.Clamp(transform.position.x, -max, max); //板条移动的x坐标范围在-max和max之间.        <span style="white-space:pre"></span>    <span style="white-space:pre"></span>transform.position = new Vector3(xPos, transform.position.y, transform.position.z);        <span style="white-space:pre"></span>}}/// <summary>/// 增加小球碰撞后的水平速度,否则小球左右反弹的效果不理想。当珠球退出碰撞时调用该方法/// </summary>/// <param name="collisionInfo">Collision info.碰撞事件</param>void OnCollisionExit(Collision collisionInfo ) {Rigidbody rigid = collisionInfo.rigidbody;//得到我们碰撞的刚体.float xDistance = rigid.position.x - transform.position.x;//碰撞的珠球与板条的水平距离，落到板条中间时，水平速度保持不变.rigid.velocity = new Vector3(rigid.velocity.x + xDistance, rigid.velocity.y, rigid.velocity.z);//刚体碰撞后的速度.}}

Block类：该脚本绑定到砖块Block中。

using UnityEngine;using System.Collections;public class Block : MonoBehaviour {/// <summary>/// 触发器/// </summary>void OnCollisionEnter () {        BreakoutGame.SP.HitBlock();        Destroy(gameObject);//删除组件}}
